是否可以以编程方式将图像添加到 toast 弹出窗口？

是的，您可以使用 setView() 方法将 imageview 或任何视图添加到 toast 通知中，使用此方法您可以根据需要自定义 Toast。

在这里，我创建了一个自定义布局文件以填充到 Toast 通知中，然后我通过使用 setView() 方法在 Toast 通知中使用了此布局。

cust_toast_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:id="@+id/relativeLayout1"
  android:background="@android:color/white">

    <TextView
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:id="@+id/textView1" android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:text="PM is here"
        android:gravity="center"
        android:textColor="@android:color/black">
    </TextView>

    <ImageView
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:src="@drawable/new_logo"
        android:layout_below="@+id/textView1"
        android:layout_margin="5dip"
        android:id="@+id/imageView1">
    </ImageView>

    <TextView
        android:id="@+id/textView2"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:text="This is the demo of Custom Toast Notification"
        android:gravity="center"
        android:layout_below="@+id/imageView1"
        android:textColor="@android:color/black">
    </TextView>

</RelativeLayout>

CustomToastDemoActivity.java

LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.cust_toast_layout, 
    (ViewGroup)findViewById(R.id.relativeLayout1));

Toast toast = new Toast(this);
toast.setView(view);
toast.show();

简单地说，使用以下内容：

Toast toast = new Toast(myContext);
ImageView view = new ImageView(myContext); 
view.setImageResource(R.drawable.image_icon); 
toast.setView(view); 
toast.show();

您可以以编程方式创建任何视图（因为我假设您询问如何在不使用 LayoutInflater 的情况下执行此操作）并在您制作的 Toast 上调用 setView。

    //Create a view here
    LinearLayout v = new LinearLayout(this);
    //populate layout with your image and text or whatever you want to put in here

    Toast toast = new Toast(getApplicationContext());
    toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(v);
    toast.show();

Knickedi 的解决方案很好，但是如果您只需要文本旁边的图标，则可以利用 Toast 具有具有相同 ID 的预定义 TextView 并在 TextView 上设置图标的事实：

Toast toast = Toast.makeText(context, text, Toast.LENGTH_SHORT);
TextView tv = (TextView) toast.getView().findViewById(android.R.id.message);
if (null!=tv) {
    tv.setCompoundDrawablesWithIntrinsicBounds(icon, 0, 0, 0);
    tv.setCompoundDrawablePadding(context.getResources().getDimensionPixelSize(R.dimen.padding_toast));

我认为我们在传递给 makeImageToast 函数的图像上显示 Toast 文本会更好......所以我对 Knickedi 代码进行了着色，并且：

public class utility  {

public static Toast makeImageToast(Context context, int imageResId, CharSequence text, int length) {
    Toast toast = Toast.makeText(context, text, length);

    View rootView = toast.getView();
    LinearLayout linearLayout = null;
    View messageTextView = null;

    // check (expected) toast layout
    if (rootView instanceof LinearLayout) {
        linearLayout = (LinearLayout) rootView;

        if (linearLayout.getChildCount() == 1) {
            View child = linearLayout.getChildAt(0);

            if (child instanceof TextView) {
                messageTextView = (TextView) child;
                ((TextView) child).setGravity(Gravity.CENTER);

            }
        }
    }

    // cancel modification because toast layout is not what we expected
    if (linearLayout == null || messageTextView == null) {
        return toast;
    }

    ViewGroup.LayoutParams textParams = messageTextView.getLayoutParams();
    ((LinearLayout.LayoutParams) textParams).gravity = Gravity.CENTER;

    // convert dip dimension
    float density = context.getResources().getDisplayMetrics().density;
    int imageSize = (int) (density * 25 + 0.5f);
    int imageMargin = (int) (density * 15 + 0.5f);

    // setup image view layout parameters
    LinearLayout.LayoutParams imageParams = new LinearLayout.LayoutParams(imageSize, imageSize);
    imageParams.setMargins(0, 0, imageMargin, 0);
    imageParams.gravity = Gravity.CENTER;

    // setup image view
    ImageView imageView = new ImageView(context);
    imageView.setImageResource(imageResId);
    imageView.setLayoutParams(imageParams);


    // modify root layout
    linearLayout.setOrientation(LinearLayout.HORIZONTAL);
    linearLayout.setBackgroundResource(imageResId);
    linearLayout.setGravity(Gravity.CENTER);
    linearLayout.setHorizontalGravity(Gravity.CENTER);
    linearLayout.setHorizontalGravity(Gravity.CENTER);
    //addView(imageView, 0);

    return toast;
}

}

这是它的用途：

utility.makeImageToast(getApplicationContext(),
                 R.drawable.your_image,"your_text",Toast.LENGTH_LONG).show();

始终有可能创建自定义布局。有一个我不喜欢的事实：它破坏了系统默认的 toast UI。这在不同的平台和实现上可能会有所不同。使用系统默认资源没有简单的方法，所以我决定破解 toast 并强制将图像放入其中。

提示：您可以像这样获取默认资源：
Toast.makeToast(context, "", 0).getView().getBackground()

这是一个助手，它将在 toast 消息前显示图像： Helper.makeImageToast(context, R.drawable.my_image, "Toast with image", Toast.LENGTH_SHORT).show()

我用它来表示成功、信息或错误。使吐司信息更好，更具表现力...

（值得一提的是，黑客基于内部 toast 使用的事实，LinearLayout因此不是系统和实现独立的。请参阅评论。）

public static Toast makeImageToast(Context context, int imageResId, CharSequence text, int length) {
    Toast toast = Toast.makeText(context, text, length);

    View rootView = toast.getView();
    LinearLayout linearLayout = null;
    View messageTextView = null;

    // check (expected) toast layout
    if (rootView instanceof LinearLayout) {
        linearLayout = (LinearLayout) rootView;

        if (linearLayout.getChildCount() == 1) {
            View child = linearLayout.getChildAt(0);

            if (child instanceof TextView) {
                messageTextView = (TextView) child;
            }
        }
    }

    // cancel modification because toast layout is not what we expected
    if (linearLayout == null || messageTextView == null) {
        return toast;
    }

    ViewGroup.LayoutParams textParams = messageTextView.getLayoutParams();
    ((LinearLayout.LayoutParams) textParams).gravity = Gravity.CENTER_VERTICAL;

    // convert dip dimension
    float density = context.getResources().getDisplayMetrics().density;
    int imageSize = (int) (density * 25 + 0.5f);
    int imageMargin = (int) (density * 15 + 0.5f);

    // setup image view layout parameters
    LinearLayout.LayoutParams imageParams = new LinearLayout.LayoutParams(imageSize, imageSize);
    imageParams.setMargins(0, 0, imageMargin, 0);
    imageParams.gravity = Gravity.CENTER_VERTICAL;

    // setup image view
    ImageView imageView = new ImageView(context);
    imageView.setImageResource(imageResId);
    imageView.setLayoutParams(imageParams);

    // modify root layout
    linearLayout.setOrientation(LinearLayout.HORIZONTAL);
    linearLayout.addView(imageView, 0);

    return toast;
}
